SPECIFICATION forming part Of Letters Patent No. 684,531, dated. October 15, 1901. Application filed August 21. 1900. serial No. 27,557. (No model.)

To :tZZ whom to may concern:

Be it known that I, ARTHUR VAN HOUWEL ING, a citizen of the United States, residing frame.

' My objects in this invention are, first, to provide an improved stacker-frame of this class in which the weight of the conveyer is carried upon the main conveyer-frame to the end that the hinged outer portion of the conveyor-frame may be made light in weight and inexpensive in construction.

.A further object is to provide means whereby this folding outer end maybe adjusted vertically with relation to the main con veyerframe from a'point at the base of the main conveyor-frame and at the same time said folding outer end may be drawn close up under the main frame from the same position.

A further object is to provide improved means whereby the main conveyer-fraine may be raised and lowered by an operator standing upon the ground at the side of the stacker.

A further object is to provide means whereby the conveyer is driven from two points-to Wit, the upwardly-moving portion thereof at the base of the stacker and the downwardlymoving portion at the base of the stacker which means shall he of simple, strong, durable, and inexpensive construction,whereby excessive strains are avoided upon the conveyor-chains at one point.

My invention consists in certain details in the construction, arrangement, and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in Which- Figure 1 shows a side elevation of the complete stacker. Fig. 2 shows a transverse sectional view through the stacker-frame to illustrate the means for winding up the ropes or cables which control the elevation of the stacker-frame. Fig. 3 illustrates diagrammatically the means for driving the endless conveyer from two points. Fig. 4c shows a top or plan view of the complete machine. Fig. 5 shows a sectional view of one side of the conveyer-t'rame, showing stub-shaft.

Referring to the accompanying drawings, I have used the reference-numeral to indicate the horizontal portion of the stacker frame.

11 indicates that portion of the stackerframe pivoted to the horizontal portion, to extend upwardly and rearwardly therefrom. This frame is hinged to the part 10 in the ordinary way. The outer end portion of the said frame ll is supported as follows: Idlers 12 are mounted on the sides of the frame at its top portion, and a pulley 13 is swiveled to a support 14, which support is connected with the threshing-machine. Near the base of the part 11 is a shaft 15,rotatably mounted in suit able bearingsand havingatone endacrank 16. On the opposite end portions of the shaft 15 are the pinions 17, which pinions are meshed with the cog-wheels 18. These cog-wheels 18 are supported upon the stub-axles 19, and connected with the cogwheels 18 are the drums 20. It is obvious that upon a rotation of the crank 16 the said drums will be turned.

Fixed to the drums 20 are the ends of a cable or rope 21. This cable is passed over the idlers 12 and around the pulley l3. I-Ienceit is obvious that by manipulation of the crank 16 the ends of the rope or cable 21 are wound upon the drums 20 and the stacker-frame 11 is raised. This may be done by an operator standing upon the ground at one side of the stacker.

In the part 10 of the stacker'frame two shafts 22 and 23 are rotatably mounted, the one above the other. On the shaft 22 are the sprocket wheels 24 to mesh with the con- Veyer-chains, Which chains are indicated by the numeral 25, and on the shaft 23 are the sprocket-wheels 26, also in mesh with the lower portion of the conveyor-chain. These two shafts 22 and 23 are driven as follows: On the ends of the shafts 22 and 23 are the cog-wheels 27 and 28, meshed with each other.

.struction to the one before described.

By this means it is obvious that the conveyer chains will be driven by power applied .to the downwardly-moving part of the conveyer and also to the upwardly-moving part. This arrangement will readily take up the slack in the downwardly-moving portion of the conveyer and prevent the excessive strains to the conveyer occasioned by applying power thereto at one point only.

To the outer end portion of the stackerframe 11 I have pivoted an auxiliary frame 31 by means of the hinges 33, and attached to this frame 11 I have pivoted an auxiliary frame 31 by means of the hinges 32, and attached to this frame is an upwardly and rearwardly projecting arm 33, supported by braces 34- and having a rope or cable 35 attached to its top portion. This rope or cable 35 is wound upon a drum 36,which drum is fixed to ashaft mounted in the machine-frame and bearing the cog-wheel 37. A gravity-pawl 38, mounted on the side of the stacker-frame, is provided to engage this cog-wheel 37, and the said cog-wheel is driven by means of a pinion 39, attached to the crank-shaft 4-0. This cable-winding device is similar in coir Hence a detailed description of its construction is deemed unnecessary. On the outer end of the frame 31 is a shaft 41, having fixed thereto the sprocket-wheels 42, over which the conveyer-chains 25 travel. I have mounted in suitable bearings atthe upperend ofthe frame 11 a shaft 43 having thereon the sprocketwheels 44, over which the conveyer-chains travel. I have also mounted on the lower surface of the upper end portion of the frame 11 the brackets 45, and in these brackets the shaft 4-6 is supported, bearing the sprocketwheels 47. The returning portion of the conveyer 25 passes over these sprocket-wheels 46. By this. means it is obvious that the frame 31 is provided with a conveyer traversing its entire length, and, furthermore, this frame 31 may be moved into any position with relation to the frame 11 withoutaffecting the operation of the conveyer. By thus attaching the idlers for supporting the conveyer-frame 11 it is obvious that all of the weight of the conveyer is supported upon the frame 11 and that on this account the extension or auxiliary frame 31 may be made light in weight and cheap in construction. It is further obvious that by placing the arms 33 at the angle shown the conveyer-frame 31 may be raised and lowered to any desirable position with relation to the frame 11 by a manipulation of the crank-shaft 40. Then when it is desired to fold up the frame 31 the frame is allowed to drop to a position where it depends straight downwardly from its hinge-joint, and obviously if the cable 35 is wound up when the conveyer-frame is at this angle, the frame 31 will be drawn to a position directly under the frame 11. Thus it may be readily and quickly folded up to occupy a minimum of space and held to a position close to the frame 11. t

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States therefor, is-- 1. In a straw-stacker, the combination of a pulley, means for supporting same from a threshing-machine, a stacker-frame pivotally connected at its lower end to move in a vertical plane, two idlers attached to the sides of the stacker-frame near its top, two drums mounted on the stacker-frame near its lower end, a rope or cable wound upon said drums at its ends, passed around said idlers, and also around said pulley, and means for winding up the drums, substantially as, andfor the purposes stated. v

2. In a straw-stacker, the combination of a support designed to be connected with a threshing-machine, a pulley attached to said support, a stacker-frame pivotally mounted at its lower end, to swing in a vertical plane,

idlers mounted on the sides of the stackerframe near its top, a crank-shaft 15 mounted upon the stacker-frame near its lower end, pinions 17 on said crank-shaft, cog-wheels 18 in mesh with said pinion and supported on the opposite sides of the stacker-frame, drums 20 connected with the cog-wheels 18, and a rope, or cable, with its central portion passed around the said pulley, then passed around the said idlers, and having its ends wound upon said drum, substantially as, and for the purposes stated.

3. In a strawstacker, the combination of a stacker-frame, a shaft mounted therein near the base of the frame, sprocket-wheels on the end portions of the shaft, two short shafts above said shaft, each of said short shafts having a sprocket-wheel, cog-wheels on the ends of said shafts, those of the upper shafts being meshed with those ofthe lower shaft, and a conveyer having sprocket-chains at its sides, passed under the upper sprocket-wheels and returning under the lower sprocketwheels, for the purposes stated.
